Any Ideas on Dealing With Blisters?

I did a little 3.5 mile run this morning (with my new Garmin 305 - very cool), and I'm still dealing with the blisters in my arches from Friday's long run, where I ran with new inserts in new shoes for 14 miles. My half marathon is 2 weeks from today. I'm going to keep training as planned (so "stop running" isn't an answer I'll consider). If you have any suggestions on how I might tape the blisters or anything that might help me avoid making them worse (I've already switched back to my old inserts), I welcome your comments. Thanks!

First Track Workout, Plus a Question

Well, I did it. I got back onto the track for a speed workout. First time in many years. It hurt a bit, but I really enjoyed it. After a 1.5 mile warmup, I ran 4 x 800 meters with 2 mins rest btwn each, followed by a 1.5 mile cooldown (5 miles total on the track). My splits for the 800s were:

3:27
3:22
3:26
3:20 (3:23.8 avg)

I wanted to run them in 3:30 (about a 7 min pace), but my track pacing skills are very rusty. As expected, my body was saying "what the heck are you doing? No lo comprendo!" (Yes, my body is often bi-lingual during times of stress). These weren't exactly "race pace" intervals, which they probably should be. There's no way I can currently sustain a 6:46 pace for anything over about 1.5 miles right now (my 5k race pace back in June was 7:12), so I'll probably have to back off the next time I do these. After my cooldown laps, my right IT band was barking a little - probably from the speed, as well as running 20 laps counterclockwise, which put more stress on the outside of that leg, so I stretched, used my foam roller and took an ice bath when I got home.

As my title suggested, I have a question for those of you who have done this: is it smart for me to start doing speedwork while I'm also trying to build up my mileage for a half marathon? Given my history of injuries, I'm a little nervous, but I really want to work on both, if it's realistic. Thoughts?

Bike ride, plus some questions for you folks

Finally got my bike off the trainer and outside for a ride today. Ended up putting in 25 miles around local neighborhoods, including some challenging hills. I'm learning that my hill running is better than my hill cycling. Hopefully I can change that before my race.

Now...I've got a couple of questions for you. Lately, after getting off the bike, my lower back has been very tight and very sore. In fact, the two weeks I didn't ride, I slept better than usual because my back didn't bother me. Well, now the back pain is back. I've never been "professionally" fitted on my bike, but have adjusted the saddle, handlebars, etc, based on what I've found online. Do any of you more experienced cyclists have any words of wisdom regarding why my lower back isn't liking the bike lately?

The other question is more frivolous. When I was a kid riding with my dad in our car, my sister and I used to play "slug bug", where we'd punch each other when we'd see a Volkswagen Beetle. I once commented to my dad that I never realized how many VW Bugs there were on the roads until I played that game. From then on, he'd refer to that phenomenon as "you just have to look for the Volkswagens and you'll see them". I know there's a term for that, but it escapes me. Okay...all that said to get to this point: I've been noticing a LOT more runners on the roads this year than I have in a long time. Yes, I started running again in Jan. of this year, but even the years I haven't run, I was still tuned in to noticing them, being a long-time runner. I think I read or heard recently that running seemed to increase during times of economic downturn. Not sure if that's the case or not. Are any of you noticing more people running lately, or is it just me?
Thanks for stopping by! Enjoy your weekend!
